I believe this is a healthy way of handling your environment. Keep negativity outside your bubble. Only keep close to you people who give you the ambition and optimism to continue. Not sure how many of you believe in this. But manifesting negativity has always brought negative outcome in my life. Surrounding myself by positive thoughts and positive people has brought a strong source of light all the time.
I could remember when I started my Bitcoin journey, my siblings all thought it was just a total waste of time I was doing back than, but I never gave up and I kept on doing what I knew how to do best, buying and investing the least amount of money I could always afford to, and today, they all now wishing had they known they would have joined me when I started my journey. So that's just exactly how life is, there will always be people out there to discourage you at all times, but it's left for you to fall for it, or hold firm to that which you believe in.
